"""
    Generated lexer tests
    ~~~~~~~~~~~~~~~~~~~~~

    Checks that lexers output the expected tokens for each sample
    under lexers/*/test_*.txt.

    After making a change, rather than updating the samples manually,
    run `pytest --update-goldens tests/examplefiles`.

    To add a new sample, create a new file matching this pattern.
    The directory must match the alias of the lexer to be used.
    Populate only the input, then just `--update-goldens`.
